Setting up a SUSE Linux 10 host name and DNS addresses

A SUSE Linux 10 machine's host name and DNS address can be easily configured following these Linux setup steps.

To set up the host name of the SUSE Linux 10 machine and the addresses of your Domain Name System servers, select the Host name and name server button. A screen like that shown in Figure 1-24 appears.

The host name of your SUSE Linux 10 machine can be anything you like, such as a person's name, a descriptive name, or something random. The only thing that you have to bear in mind is that the host name and domain name can contain only letters and numbers as well a hyphen or an underscore. The host name can be only one string of characters and cannot contain a space or a period. As the name suggests, the domain name dictates the network domain that this machine falls into. This domain may well be something in line with your company's policy or could be something you have set up yourself.

When integrating a new system into an existing networked environment, you should always follow the same naming conventions that are already being used, especially for the domain name. If you do not, other systems on the network may not be able to locate your system correctly, and certain services on your system may not be able to interoperate with existing network services.


Figure 24

Enter the name server address into the Name Server 1 field. You can also enter up to two other separate DNS server entries. Your administrator or ISP should be able to give you this information.

The Domain Search entry is used to control how your machine looks up the address of other machines connected through TCP/IP. For example, if you use a Domain Search entry such as suse.com, you can communicate with any machine in the SUSE domain by just its host name. For example, with suse.com as the Domain Search entry, you can communicate with the machine you are setting up in this example by just using the host name of bible. If you do have suse.com as a Domain Search field, however, you have to specify the fully qualified domain name of the machine you want to communicate with (in the case of this example, that is bible.suse.com).

When you have set the DNS configuration for your system, press OK to save your changes.
